Cheapest: find someone with a laser cutter, cut out some plexi circles, print out official Infinity markers, glue them on the bottom. Much cheaper. MAS is kinda pricy but you pay them for the effort if you want to get MAS cheaper, IIRC IJW (wargamingtrader.com?) and ChoKonnit sell them by piece a bit chezper than the official price. Also, get 15mm once they come out.

Full loadout for CA:- camo (at least 4, if you want to run Shasvastii-heavy or sectorial then at least 12)- TO camo (2, plus one 40mm for Sphinx if you plan to use it)- Impersonation (1 yellow/red set for now)- mines (3)- order tokens (16 regular, 6-8 irregular, 8? impetuous), these can be substituted with colored beads or something- LT token- 3 command tokens- 3 sepsitorized tokens (if you plan to run EI constructs)- 8-10 wound markers- 8-10 unconscious- 10 prone- spawn-embryo for each Shasvastii- 2 Tinbots- 5-6 Sniffers- 8 blank white plexi markers (something like 15x35 mm) to write status effects on with a dry-erase marker, forget about all the seldom-used ones- 1 set of templates (circular, small teardrop, large teardrop)- 1 set of silhouettes- if you use Daturazis (if not, you will), 4+ paper smoke templates (or at least small tokens to mark smoke center)
